antd vue pro 多页签配置操作，具体操作如下。

1.引入 tagviews文件

  在 store/modules 中创建 tagviews.js ，复制一下代码到文件中保存

const state = {
  visitedViews: [],
  cachedViews: []
}

const mutations = {
  ADD_VISITED_VIEW: (state, view) => {
    if (state.visitedViews.some(v => v.path === view.path)) return
    state.visitedViews.push(
      Object.assign({}, view, {
        title: view.meta.title || 'no-name'
      })
    )
  },
  ADD_CACHED_VIEW: (state, view) => {
    if (state.cachedViews.includes(view.name)) return
    if (view.meta && view.meta.isCache) {
      state.cachedViews.push(view.name)
    }
  },

  DEL_VISITED_VIEW: (state, view) => {
    for (const [i, v] of state.visitedViews.entries()) {
      if (v.path === view.path) {
        state.visitedViews.splice(i, 1)
        break
      }
    }
  },
  DEL_CACHED_VIEW: (state, view) => {
    const index = state.cachedViews.indexOf(view.name)
    index > -1 && state.cachedViews.splice(index, 1)
  },

  DEL_OTHERS_VISITED_VIEWS: (state, view) => {
    state.visitedViews = state.visitedViews.filter(v => {
      return v.meta.affix || v.path === view.path
    })
  },
  DEL_OTHERS_CACHED_VIEWS: (state, view) => {
    const index = state.cachedViews.indexOf(view.name)
    if (index > -1) {
      state.cachedViews = state.cachedViews.slice(index, index + 1)
    } else {
      state.cachedViews = []
    }
  },

  DEL_ALL_VISITED_VIEWS: state => {
    // keep affix tags
    const affixTags = state.visitedViews.filter(tag => tag.meta.affix)
    state.visitedViews = affixTags
  },
  DEL_ALL_CACHED_VIEWS: state => {
    state.cachedViews = []
  },

  UPDATE_VISITED_VIEW: (state, view) => {
    for (let v of state.visitedViews) {
      if (v.path === view.path) {
        v = Object.assign(v, view)
        break
      }
    }
  },

  DEL_RIGHT_VIEWS: (state, view) => {
    const index = state.visitedViews.findIndex(v => v.path === view.path)
    if (index === -1) {
      return
    }
    state.visitedViews = state.visitedViews.filter((item, idx) => {
      if (idx <= index || (item.meta && item.meta.affix)) {
        return true
      }
      const i = state.cachedViews.indexOf(item.name)
      if (i > -1) {
        state.cachedViews.splice(i, 1)
      }
      return false
    })
  },

  DEL_LEFT_VIEWS: (state, view) => {
    const index = state.visitedViews.findIndex(v => v.path === view.path)
    if (index === -1) {
      return
    }
    state.visitedViews = state.visitedViews.filter((item, idx) => {
      if (idx >= index || (item.meta && item.meta.affix)) {
        return true
      }
      const i = state.cachedViews.indexOf(item.name)
      if (i > -1) {
        state.cachedViews.splice(i, 1)
      }
      return false
    })
  }
}

const actions = {
  addView ({
    dispatch
  }, view) {
    dispatch('addVisitedView', view)
    dispatch('addCachedView', view)
  },
  addVisitedView ({
    commit
  }, view) {
    commit('ADD_VISITED_VIEW', view)
  },
  addCachedView ({
    commit
  }, view) {
    commit('ADD_CACHED_VIEW', view)
  },

  delView ({
    dispatch,
    state
  }, view) {
    return new Promise(resolve => {
      dispatch('delVisitedView', view)
      dispatch('delCachedView', view)
      resolve({
        visitedViews: [...state.visitedViews],
        cachedViews: [...state.cachedViews]
      })
    })
  },
  delVisitedView ({
    commit,
    state
  }, view) {
    return new Promise(resolve => {
      commit('DEL_VISITED_VIEW', view)
      resolve([...state.visitedViews])
    })
  },
  delCachedView ({
    commit,
    state
  }, view) {
    return new Promise(resolve => {
      commit('DEL_CACHED_VIEW', view)
      resolve([...state.cachedViews])
    })
  },

  delOthersViews ({
    dispatch,
    state
  }, view) {
    return new Promise(resolve => {
      dispatch('delOthersVisitedViews', view)
      dispatch('delOthersCachedViews', view)
      resolve({
        visitedViews: [...state.visitedViews],
        cachedViews: [...state.cachedViews]
      })
    })
  },
  delOthersVisitedViews ({
    commit,
    state
  }, view) {
    return new Promise(resolve => {
      commit('DEL_OTHERS_VISITED_VIEWS', view)
      resolve([...state.visitedViews])
    })
  },
  delOthersCachedViews ({
    commit,
    state
  }, view) {
    return new Promise(resolve => {
      commit('DEL_OTHERS_CACHED_VIEWS', view)
      resolve([...state.cachedViews])
    })
  },

  delAllViews ({
    dispatch,
    state
  }, view) {
    return new Promise(resolve => {
      dispatch('delAllVisitedViews', view)
      dispatch('delAllCachedViews', view)
      resolve({
        visitedViews: [...state.visitedViews],
        cachedViews: [...state.cachedViews]
      })
    })
  },
  delAllVisitedViews ({
    commit,
    state
  }) {
    return new Promise(resolve => {
      commit('DEL_ALL_VISITED_VIEWS')
      resolve([...state.visitedViews])
    })
  },
  delAllCachedViews ({
    commit,
    state
  }) {
    return new Promise(resolve => {
      commit('DEL_ALL_CACHED_VIEWS')
      resolve([...state.cachedViews])
    })
  },

  updateVisitedView ({
    commit
  }, view) {
    commit('UPDATE_VISITED_VIEW', view)
  },

  delRightTags ({
    commit
  }, view) {
    return new Promise(resolve => {
      commit('DEL_RIGHT_VIEWS', view)
      resolve([...state.visitedViews])
    })
  },

  delLeftTags ({
    commit
  }, view) {
    return new Promise(resolve => {
      commit('DEL_LEFT_VIEWS', view)
      resolve([...state.visitedViews])
    })
  }
}

export default {
  namespaced: true,
  state,
  mutations,
  actions
}

2. tagviews文件引用

 （1）在 store/getters.js 引入

const getters = {
  .....
// 下方两句关键代码

  visitedViews: state => state.tagsView.visitedViews,
  cachedViews: state => state.tagsView.cachedViews
}

export default getters

 （2）在 store/index.js 引入

....其他代码
// 关键代码
import tagsView from './modules/tagviews'

.... 其他代码
export default new Vuex.Store({
  modules: {
    app,
    user,
    permission,
    // 关键代码
    tagsView
  },
  state: {

  },
  mutations: {

  },
  actions: {

  },
  getters
})

3. 更改routeview.vue 文件

 在 layouts/RouteView.vue 直接替换成以下代码

<template>
  <keep-alive :include="cachedViews">
    <router-view :key="key" />
  </keep-alive>
</template>
<script>
export default {
  name: 'RouteView',
  computed: {
     cachedViews () {
        return this.$store.state.tagsView.cachedViews
      },
      key () {
        return this.$route.fullPath
      }
  },
  props: {
    keepAlive: {
      type: Boolean,
      default: true
    }
  },
  data () {
    return {}
  }

}
</script>

4.更改mutiltable.vue文件

在components/MultiTab/MultiTab.vue 中直接替换以下代码

<script>
import events from './events'

export default {
  name: 'MultiTab',
  data () {
    return {
      fullPathList: [],
      pages: [],
      activeKey: '',
      newTabIndex: 0
    }
  },
  created () {
    // bind event
    events
      .$on('open', (val) => {
        console.log('table_open', val)
        if (!val) {
          throw new Error(`multi-tab: open tab ${val} err`)
        }
        this.activeKey = val
      })
      .$on('close', (val) => {
        if (!val) {
          this.closeThat(this.activeKey)
          return
        }
        this.closeThat(val)
      })
      .$on('rename', ({ key, name }) => {
        console.log('rename', key, name)
        try {
          const item = this.pages.find((item) => item.path === key)
          item.meta.customTitle = name
          this.$forceUpdate()
        } catch (e) {}
      })

    this.pages.push(this.$route)
    this.fullPathList.push(this.$route.fullPath)
    this.selectedLastPath()
  },
  methods: {
    onEdit (targetKey, action) {
      this[action](targetKey)
    },
    remove (targetKey) {
      const newVal = this.getPage(targetKey)
      this.pages = this.pages.filter((page) => page.fullPath !== targetKey)
      this.fullPathList = this.fullPathList.filter((path) => path !== targetKey)

      if (newVal != null) {
        this.$store.dispatch('tagsView/delView', newVal)
      }
      // 判断当前标签是否关闭，若关闭则跳转到最后一个还存在的标签页
      if (!this.fullPathList.includes(this.activeKey)) {
        this.selectedLastPath()
      }
    },
    selectedLastPath () {
      this.activeKey = this.fullPathList[this.fullPathList.length - 1]
    },
    getPage (targetKey) {
      const newVal = this.pages.filter((c) => c.fullPath === targetKey)
      return newVal.length > 0 ? newVal[0] : null
    },
    // content menu
    closeThat (e) {
      // 判断是否为最后一个标签页，如果是最后一个，则无法被关闭
      if (this.fullPathList.length > 1) {
        this.remove(e)
      } else {
        this.$message.info('这是最后一个标签了, 无法被关闭')
      }
    },
    closeLeft (e) {
      const currentIndex = this.fullPathList.indexOf(e)
      if (currentIndex > 0) {
        this.fullPathList.forEach((item, index) => {
          if (index < currentIndex) {
            this.remove(item)
          }
        })
      } else {
        this.$message.info('左侧没有标签')
      }
    },
    closeRight (e) {
      const currentIndex = this.fullPathList.indexOf(e)
      if (currentIndex < this.fullPathList.length - 1) {
        this.fullPathList.forEach((item, index) => {
          if (index > currentIndex) {
            this.remove(item)
          }
        })
      } else {
        this.$message.info('右侧没有标签')
      }
    },
    closeAll (e) {
      const currentIndex = this.fullPathList.indexOf(e)
      this.fullPathList.forEach((item, index) => {
        if (index !== currentIndex) {
          this.remove(item)

      })
    },
    refreshPage (e) {

                }

5.生成路由地方配置，本文路由生成在 permission.js中，具体位置看项目

 注意事项：

        1、每个路由的name必须跟页面内的name一致，否则不会缓存

        2、路由当中的isCache 是控制多页签是否缓存重要属性（可自己控制是否缓存开关）

至此流程结束，多页签功能完成
